5. Copolymers of the TAT monomer (shown below) have been prepared and studied for solar cell applications. The preparation of this monomer starts from a tetrahalogenated phenyl ring, which can be converted into the tetrathienophenyl intermediate shown using cross-coupling reactions. Identify this tetrahalogenated phenyl starting material, and demonstrate how it could be converted into the intermediate.
